2014-09-20 I surely learned a lot about Unix in the last years, but I'm still missing basic knowledge. There was this thread in DFDE today. [0] The guy had a full disk. `df' displayed, that it was 100% used with 0 free blocks, although the disk had more blocks than those used. Cosmac explained that these blocks were reserved for root. This was new to me, but I could verify it: $ df / | awk 'NR>1{print; print "blocks usable:", $3+$4}' /dev/sda1 7827080 6756260 673216 91% / blocks usable: 7429476 400MB (= 5%) reserved for root. This was delighting today: To learn something so fundamental after ``all these years''. This reminds me of times when discov- ering new stuff in Unix was the usual thing. In some way, this knowledge that I have today makes my computer life more boring ... [0] https://debianforum.de/forum/viewtopic.php?f=32&t=151375 http://marmaro.de/lue/ markus schnalke
